Is it possible to add a vertical line to a ggplot graph with data of class Week on the x-axis? For example
library(tsibble) #> #> Attaching package: 'tsibble' #> The following objects are masked from 'package:base': #> #> intersect, setdiff, union library(ggplot2) #> Warning: package 'ggplot2' was built under R version 4.1.3 DF <- data.frame(dt = yearweek("2000W01") + 0:20, val = 0:20) ggplot(DF, aes(x=dt, y=val)) + geom_point() + geom_vline(xintercept = as.numeric(yearweek("2000 W10")))

Note that no error message appears; the graph simply appears without any vertical line.
Any help greatly appreciated.
